778111592b dvenc: initialize the profile only once, at init 
We do not allow the frame parameters to change during encoding, so there
is no need to do this for each frame.

so do not even attempt to decode them and skip them instead.

e7fc5d53a0 huffyuv: change statistics initialization 
Normally, a Laplace distribution is more typical of the residuals
encoded, but for noisy input, it's both better and simpler to be
safe and use a 1/d^2 distribution. Second hunk could use some
renormalization but it has effectively little impact.

Output size of ffvhuff on various 4:2:0 sequences:
context=0,1/d:    851974   27226   1137281
context=0,1/d²:   619081   25069   1051500
context=0,1/d³:   501983   30454   1290561

5039aadf68 avcodec/ass: explicit PlayRes[XY] 
This avoids the following libass warning when using the subtitles
filter: "Neither PlayResX nor PlayResY defined. Assuming 384x288"

Subtitles tests change because the output is ASS and the PlayRes[XY]
ends up in the output.

f6577bd9cf huffyuvdec: use unsafe bitstream reader 
The reader reads in chunks of 11 bits at most, and at most 3 times. The unsafe
reader therefore may read 6 chunks instead of 1 in worst case, ie 8 bytes,
which is within the padding tolerance.

The reader ends up being ~10% faster. Cumulative effect of unsafe reading and
code block swapping on 3 sequences is for 1 thread, decoding time goes from
23.3s to 19.0s.
